Problems solved by technology

After the laser is used to burn the photoresist coating on the glass disk, the developer should be used to develop the burnt point, and then use deionized water to add water to the inner ring and spin the water to wash it, so that the surface of the resin will form pits. This method Usually, defects will be generated at the corners of the outer edges of the pits due to the accumulation of water washing, and the forming pits will be distorted, resulting in an increase in the time jitter value of the metal master and an increase in the bit error value.

Embodiment 1

[0011] Water-based polyester varnish 47%, brand: Z-13-01, molecular weight (Mn) 2000-5000, this component is the main component of water-based repair fluid film-forming, after drying and curing to form the required solid film; polyether modified 1% non-toxic silicone oil, grade BYK-306 or BYK-300, 4% low molecular weight polyethylene, grade OPE, the rest is deionized water, the unit is percent by weight, the same below. After repairing the pits, this formula can make the metal master disk obtain the result that the maximum random bit error rate is only 18, and the average time jitter is 21 nanoseconds, which is an ideal formula. When preparing, put the above ingredients into a stainless steel container and stir for about 2 hours, then filter and use.

Embodiment 2

[0013] Water-based polyester varnish 51%, grade: Z-13-01, molecular weight (Mn) 2000-5000, polyether type modified silicone oil 3%, grade BYK-306 or BYK-300, low molecular polyethylene 5%, grade OPE. After repairing the pits, this formula can make the metal master disk obtain the result that the maximum random bit error rate is only 13, and the average time jitter is 19 nanoseconds, which is also an ideal formula. Preparation method is the same as embodiment one. Embodiment three

[0014] Water-based polyester varnish 49%, grade: Z-13-01, molecular weight (Mn) 2000-5000, polyether type modified silicone oil 5%, grade BYK-306 or BYK-300, low molecular polyethylene 8%, grade OPE. After repairing the pits, this group can achieve a maximum random bit error rate of 32 and an average time jitter of 24 nanoseconds for the metal master disc. Compared with the above-mentioned group, the technical indicators of this group are slightly lower. Preparation method is the same as embodim...

Abstract

The invention relates to electronic chemical materials, in particular to a water-soluble repair solution for recording resin information surfaces. According to the design scheme provided by the present invention, the water-soluble repair solution for recording resin information surface is mainly composed of 49±2% water-based polyester varnish and 3-8% leveling agent, and the rest is deionized water, the unit is percent by weight . The leveling agent includes 1-3% of polyether-type modified silicone oil and 2-5% of low-molecular-weight polyethylene, and the unit is parts by weight. When this kind of repair liquid is used to repair the surface of the recording resin information pits, the surface of the pits after recording can be made smoother, and the defects at the corners of the pits can be repaired in time to ensure that the produced master discs will not be affected by time shaking indicators and errors. The code index is improved, so that the produced disc has high performance.

Description

technical field [0001] The invention relates to electronic chemical materials, in particular to a water-soluble repair solution for recording resin information surfaces. Background technique [0002] The production of metal master discs for optical disc production is first carried out on optical glass discs. After the laser is used to burn the photoresist coating on the glass disk, the developer should be used to develop the burnt point, and then use deionized water to add water to the inner ring and spin the water to wash it, so that the surface of the resin will form pits. This method Usually, the accumulation of water at the corners of the outer edges of the pits will cause defects to occur, and the formed pits will be distorted, resulting in an increase in the time jitter value of the metal master and an increase in the bit error value. Contents of the invention [0003] The purpose of the present invention is to design a water-soluble repair liquid for recording resi...
